That's a real doozie bazz , heard of some strange shit happening to Patrols but that's just weird , if I had to guess I'd be thinking a bush or bearing that when it heats up moves, crushes or distorts in some way .Quote:

All bushes & bearing have been checked multiple times and tyres rotated. It did it on another set of MUDS but only slightly on the original mags and standard tyres. I haven't tried a "on car balance" yet, but I will as it's the only thing I haven't done.Quote:

Further to this get some one who knows how to balance 4WD tyresQuote:

In the end though I repacked the swivel hub bearings and removed a shim from all four bearing caps to increase the preload, and the wobbles have gone completely. No shudder or shimmy, and no wobble anywhere anymore. In MY case, it was definitely the swivel hub bearings. Might be worth looking into....
Write a check list of every steering, axle and suspension component under the Patrol and tick them off as you get them checked. The lower, Panhard rod bush is common to fail on the Patrol. If you look at one you will see why. A small rubber bush is all it is. They can wear out easily.
My Patrol had the wobbles. But it disappeared after doing a complete front end overhaul, of bearings and all bushes. Then stupid me thought it would be great to get some nice looking alloys to mount the AT's on. Then it came back, but not as bad. So I live with it.
I think its got a lot to do with the rims. Factory steelies are crap from new. Cheap sunnies wouldn't be any better. I have ROH Sunraysia steelies on my 35's (also were on my 33 AT's) and they have zero wobble. This, the lower panhard rod bush and incorrectly adjusted wheel bearings I think are the key factors. Maybe even tyres, the cheap ones on the market, who knows. Cheap large rubber can't be made that well can they?
My woobble at 80ks was loose wheel bearings never had a problem since
I can see your logic. I also thought the aftermarket steelies I run may have something to do with it, but it dont explain my issue. I have 33" BFG Muds on King rims. I have had the rims checked out and found no issues. A while ago, my tyre shop identified a slightly "out of round tyre" which we thought was causing the wobble issue, but after swapping to the spare, it went away for a while but eventually came back.Quote:

Maybe I have one or two "soft" compound tyres causing the wobbles when hot. It gets all too hard and I get a headache thinking about it.
Yeah you just reminded me John. My wheel bearings kept coming lose. Found out the sub axles had a wear groove where the inner wheel bearing sits against. New stub axles and retentioned bearings and alls good.Quote:
